ROBERT BURNS, OF CHICAGO, ILLINOIS.

CAR JOURNAL-BOX.

SPECIFICATION forming part of Letters Patent No. 714,095, dated November 18, 1902.

Application filed March 5,1901. Serial No. 49,924. (No model.)

T0 @ZZ whom t may concern.-

Be it known that I, ROBERT BURNS, of Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Car Journal-Boxes; and I do herebydeclare that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawings, and to the letters of reference marked thereon, which form a part of this specification.

This invention relates to a novel journal box for car-axles constructed to prevent the abstraction by unauthorized persons from the box of the bearing-brass which receives the wear of the axle.-

The invention consists in the matters hereinafter set forth, and more particularly pointed out in the appended claims.

As journal-boxes for railway-cars are at present constructed the bearing-brasses may be readily removed therefrom by raising the box with a suitable lifting device a distance sufficient to permit the brasses to be raised clear of the flanged ends of the journals. As a result of this prevailing construction in journal-boxes in common use itis easily possible for large numbers of bearing-brasses to be annually stolen from cars, the work of abstracting the same from the boxes being so small as to enable the same to be removed in a very short time and without exciting suspicion. As a result great loss is sustained by railroad companies, and the apprehension of the thieves requires a great deal of skill and entails much expense and annoyance.

Moreover, the loss of the bearing-brasses is often not discovered until the axle has been ruined by running in contact with the hard material of the box.

It is the purpose of my invention to provide means which may be embodied in new journal-boxes or which may be attached to boxes already in use which will prevent the jour lated with my invention. Fig. 3 is a trans- ,verse section on line 3 8 of Fig. 2.

Fig. l, A designates the journahbox, provided with the usual hinged/door or lid A; B, the axle therein, and C the brass, on the concave lower surface of w ich is formed the bearing-surface for the axle and secured in the box in any suitable manner.

AThe lower wall of the box is provided about midway between the ends thereof with a thickened portion D, having the form of a short vertical tube-7 the upper end of which projects above the lower wall of the box and the lower end of which depends a distance below the box. YWithin the bore of said tube is located a stop-stud E, which has screw-threaded connection with the tube and which projects upwardly therefrom a distance into the box, said stud terminating below the axle B. "The stud is slotted at its lower end, whereby it may be engaged by a suitable tool to move the stud toward and away from the axle. The stud is locked in position within the tube by means of a short locking-stud F, which has screw-threaded engagement with the bore of the tube, permitting it to be moved toward and away from the stud E. The locking-stud is provided with an angular head f, adapted to be engaged by a socketed tool to turn the same into and out of its locking position. The stopstud is adj usted to its proper position before the locking-stud is inserted into place, and

thereafter the locking-stud is moved up against the stop-stud to hold it in place.

' In order to prevent access by an unauthor- IOO In practice a special tool or implement is provided for removing the several parts of the device described, consisting of a thin plate-wrench, which enters the groove g of the nut, and a shank having on one part a socket to receive the lower end of the locking-stud and on another part a tapered end to enter the slotted end of the stop-stud.

When the parts are in the position shown in Fig. l, it will be seen that if an attempt be made to raise the box the stop-stud will come in contact with the axle before the box has been raised suflciently to permit the brass to clear the axle, so as to enable the same to be removed. Before the box can be removed,

therefore, the stop-stud must be lowered, which cannot be accomplished Without removing the cap and lowering the locking-stud. It will be observed, therefore, that a person not provided with an implement such as before mentioned cannot quickly abstract the bearing-brass from the box, and in order that an unauthorized person may gain access to the box, therefore, a greater amount of time is required than the conditions would warrant, so that the chances of the brasses beingv stolen are practically eliminated.

When a new brass is to be substituted by an authorized person, the cap and lockingstud are removed and the stop-stud lowered the required distance. The box is then raised by a suitable lifting device, as a jack, until sufcient space is provided between the axle and the box to clear the brass. A new brass is then substituted, the box lowered, and the parts of the safety device again adjusted to the positions shown i'n Fig. l.

In Fig. 4 I have shown my improvements constructed to be applied to a box already in use. In said construction the tube H is removably connected with the box, being inserted from the interior of the box through an opening in the lower wall thereof. Said tube is provided with a head or llange h, which extends laterally beyond the opening into horizontal bearing engagement with the bottom wall of the box.l The tubeis provided on each side thereof below the flange h with lateral lugs h, which fit Within sockets in the lower wall of the box, preventing said tube from rotating with respect to the box.

A lock-nut I-I has screw-threaded engagement with the lower exposed end of said tube and bears against the lower surface of the box and locks the tube from vertical movement. The other parts of the device are shown as made like the similar parts in Fig. 1 and before described, and said parts are designated by like reference-letters.

It is obvious that many changes may be made in the details of construction, in the size, and proportions without departing from the spirit of myinvention, andI do not wish, therefore, to be limited to such details except as hereinafter made the subject of specic claims.

I claim as my invention- 1. The combination with a carjournal-box, a removable bearing-brass and an. axle journaled therein, said box being provided at its end with an opening through which the brass is inserted into and removed from the box, of means for preventing unauthorized removal of said brass comprising a removable stop located opposite to the bearing-brass and closely adjacent to but out of contact with the axle, the brass being made of such thickness relatively to the space below the axle and to the distance between the axle and stop, when the latter is in its uppermost position, that said brass may be removed from or inserted into the box when the stop is retracted from the axle and without removal of the axle but cannot be removed from or inserted into the box when the stop occupies its normal uppermost position.

2. The combination with a car journal-box constructed to permit the removal and replacement of its bearing-brass without removal of the journal, of a stop arranged opposite the seat of the bearing-brass and normally removed from but closely adjacent to the periphery of a journal located in said box, said stop being movable nearer to or farther from 'the seat of the bearing-brass, substantially as described.

3. The combination with a car journal-box having a removable bearing-brass,and a shaft or axle journaled therein, of means to prevent unauthorized removal of said brass consisting of a movable stop located opposite the bearing-brass of the box and adjacent to but normally out of contact with the shaft or axle, substantially as described.

It. A car journal-box having means to prevent unauthorized removal of the bearingbrass, said means consisting of an adjustable stop arranged opposite the seat of the brass, and means for locking said stop in adjusted positions, substantially as described.

5. The combination with a journal-box and a brass removably seated therein, of a stop arranged opposite to the seat of the brass and movable toward and from said seat, said stop being designed to prevent the raising of the box from an axle j ournaled therein suticiently to permit the removal of the brass without disassembling of the parts of the box.

6. A journal-box provided in its lower wall with a non-rotative removable tubular part which projects below said box, a verticallymovable stop-stud located in the tubular part and projecting into the box, a locking-stud engaging the stop-stud, and a closing-cap fitted to the lower end of the tubular part, substantially as described.

7. A journal-box provided in its lower wall with a non-rotative removable tubular part extending through the lower wall of the box and provided with radial lugs which engage notches in the wall of the box, a locking-ring having screw-threaded engagement with the IOO IIO

tubular part and bearing against the wall of of two witnesses, this 27th day of February, the box, astop-stud movable vertioallywithin A. D. 1901.

said tubular part and projecting into the box, and means for closing the lower end of said ROBERT BURN part, substantially as described. Witnesses:

In testimony that I claim the foregoing as WILLIAM L. HALL,

my invention I affix mysignature, in presence C. H. NEALE.
